A gas lift system improves the recovery of petroleum fluids from a well to the surface through production tubing. The gas lift system has a packer and a lower injection mandrel connected to the production tubing below the packer. The gas lift system further includes a gas lift module connected to the production tubing above the packer, and an injection line that carries pressurized gas from the surface to both the lower injection mandrel and the gas lift module. An upper injection line valve assembly is configured to provide a source of pressurized gas from the injection line to the gas lift module, while an injection line gas lift valve assembly is configured to provide a source of pressurized gas from the injection line to the lower injection mandrel.

A flow regulation tool including a ported landing nipple having a port therethrough, a retrievable choke assembly disposed within the housing, the choke assembly including a choke member and a pressure port, a fluid flow path within the housing that includes a first direction of flow in a first portion of the flow path and a second direction of flow in a second portion of the flow path, and a sensor gauge having first and second pressure sensing points disposed in the retrievable choke assembly, the first pressure sensing point exposed to pressure upstream or downstream of the choke member depending upon fluid flow direction and the second pressure sensing point exposed to pressure at the other of upstream or downstream of the choke member depending upon fluid flow direction, one of the first and second pressure sensing points exposed to the corresponding pressure through the pressure port.

A rupture disk. The disk includes a body having an inside surface defining a hollow therein and a fluid port disposed to make fluid connection between the hollow and a fluid pressure source. A method for operating a wellbore includes applying pressure though the port of a disk, and rupturing the disk with the applied pressure.

A side pocket mandrel is configured for use within a gas lift system deployed in a well that has an annular space surrounding the gas lift system. The side pocket mandrel includes a central body that includes a central bore, a gas lift valve pocket, and a gas lift valve installed within the gas lift valve pocket. The side pocket mandrel may also include a motorized choke valve assembly to selectively cover some or all of an internal tubing port extending between the central bore and the gas lift valve pocket. The side pocket mandrel may also include an automatic closing valve assembly configured to automatically close the gas lift valve port when the gas lift valve is removed from the side pocket mandrel.

Electric remote operated gas lift mandrel

A side pocket mandrel for use within a gas lift system is configured to permit the exchange of valve pockets. The side pocket mandrel has a central body, a receiver that is laterally offset from the central body, and a valve pocket that is removably secured to the receiver. The valve pocket can be configured for a threaded connection with the receiver to permit the facilitated exchange of modular valve pockets at the receiver. Gas from the valve pocket can be carried to the central body of the side pocket mandrel through one or more external gas lines or one or more internal gas injection passages.

An open tip downhole expansion tool incudes a frustoconical member having a base and a tip, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer compliance area in a material of the member along a length of the radially outer zone; and an inner compliance area in a material of the member along a length of the radially inner zone, the outer and inner compliance areas being located at different positions along the axial length of the frustoconical member, the outer and inner compliance areas each causing the frustoconical member to present a first resistance to deformation when the compliance areas are in a first condition and a higher resistance to deformation of the frustoconical member when the compliance areas are in a second condition.

An open tip downhole expansion tool including a frustoconical member having a base at a diametrically smaller portion of the frustoconical member and a tip at a diametrically larger portion of the frustoconical member, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer void in a material of the member along a length of the radially outer zone; and an inner void in a material of the member along a length of the radially inner zone, the outer and inner voids being located at different positions along the axial length of the frustoconical member, the outer and inner voids each causing the frustoconical member to present a first resistance to deformation when the voids are open and a higher resistance to deformation of the frustoconical member when the voids are collapsed.
